MEANS FOR OALKING PIPE-JOINTS- Specification of Letters Patent. I

Patented June 4, 1907.

Application filed April 2,1906. Serial No. 309,453.

To all whom iv'.may concern: y

Be it known that 1, PETER E. SNOW, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and a useful Improvements in Means for Calking Pipe- Joints; and I do declare the following to be a full, clear, and exact description of the invention, such as. will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a' part of this specification.

My invention relates to improvements in means for calking pipe joints.

My object is to do awaywith the old means of calking and substitute what I term a calking ring consisting preferably of lead adapted to be interposed in a cold state between the telescoping extremities of the pipe ends to be joined and forced therein in such a manner as to make a perfectly tight joint.

Heretofore so far as I am aware these .joints have been formed by placing hemp, oakum or similar vegetable substance in the first instance between the two overlapping ends and after forcing the same tightly in place, molten lead is applied above the oakum whereby the space between the two ends to be joined is filled.

The object of using the oakum or similar material is to prevent the molten lead from escaping by running out between the. pipe ends. The oakum or other vegetable packing not only makes an insecure support for the lead, but in time it decays with the result that the joint leaks. My improved means for forming these-joints is not only much more simple and less troublesome to use, but makes a permanent and absolutely secure joint, being one that will'last as lon as the pipe 6, thus obviating the necessity of renewing the joint at intervals.

Having outlined my improvement together with some of its advantages, I will proceed to describe the same in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure 1' is a detail view in side elevation of what I term my improved calking ring. Fig.2 is a top plan view of\the same. Fig. 3 is a sectiontaken the body of the pipe 6.

on the line 3+3 Fig. 2. Fig. 4 is a sectional view of the bell end of a piece of iron pipe. Fig. 5 is a similar view of the opposite end, adapted to enter the bell end of the other pipe member in forming a joint. In Fig. 5 the calking ring is shown applied to the joint but on a much larger scale than in Figs. 1 to 3 inclusive. Fig. 6 is a sectional View of the pipe ends shown in the assembled relation and after the joint is completed by the use of my improvement.

The same reference characters indicate the same parts inall the views.

Let the numeral 5 designate one pipe section and 6 the other section. The section 5 is provided with an enlarged or bell extremity 7 adapted to receive the extremity of the opposite pipe section 6 after the calking ring 8 is applied thereto. The section 6 is usually provided with a slight circumferential reinforcement or collar 9 forming a shallow shoulder a short distance from the end of the p lIIy improved calking ring is originally of the construction shown in Figs. 1 and 2. Let the numeral 10 designate the rim in its entirety. This rin as originally mo ded is provided with a cy ndrical base 12 and an upper portion 13 somewhat enlarged and provided with alternating interior and exterior longitudinally disposed grooves 14. The ring is originally provided with these grooves so that afterward its circumference may be reduced by hammering it toward the pipe 6 whereby it is caused to assume the position shown in Fig. 5. As the grooved portion of the ring is reduced in circumference by compression or hammering, the metal will gradually fill up the grooves at least to a certain extent.

In applying the calking ring to the pipe member 6, the part 12 of the ring is applied to the shouldered or reinforced part 9 of the pipe, the part 12 being preferably made ofa size to fit or ap roximately fit this part of the pipe. When t e ring is first applied the upper or grooved portion 13 stands out from hammers the portion 13 toward the pipe until it is caused to fit the same closely. T e extremity of the pipe 6 equipped with the calking ring when in the position shown in Fig.- 5, is inserted in the bell extremity 7 of the pipe member 5 'A calking iron is then The operator then applied to the outer exposed edge of the calking ring and the latter is forced inwardly between the two telescoping pipe extremities until the cold lead is caused to assume the position approximately shown in Fig 6 making a perfectly tight joint, and one that is exceedingly durable.

It sometimes happens that the sewer pipe sections are not of perfectly regular forma-' tion. In other words when the member 6 is inserted in the bell end of the member 5, the edge of the pipe 6 while touching the shoulder of the bell a portion of the distance may not be engaged the entire distance owing to the said irregularity. My improved calking ring is adapted to overcome this difficulty and make a perfectly tight joint as well where the edge of the pipe 6 does not engage the shoulder of the bell as where it does so engage. This feature is illustrated in Fig. 6 in which the pipe 6 is shown engaging the shoulder of.

the bell on the lower side of the view, while it is separated therefrom but filled with the calking ring on the upper side of the view.

Attention is called to the fact that the.

grooves of the ring facilitate both expansion and contraction of the same and may be arranged in any suitable manner.

Having thus described my invention, what I claim is: i

1. A calking ring having a cylindrical base and interiorly alternating V-shaped longitudinally dis osed grooves.

3. A cal ing ring having one portion larger than the other portion, the larger ortion being provided with longitudinal y disposed grooves to facilitate the reduction of the rings diameter by inward pressure or hammering. j

4. A calking ring composed of lead having a plain base portion and a frustum-shaped grooved portion for the purpose set forth.

5. In means for forming pipe joints, the combination of the pipe sections to be joined, one having a bell end and the other a reduced end adapted to enter the bell end, andan interposed soft metal calking ring, provided with grooves to' facilitate expansion and contraction.

6. In a pipe joint, the combination of the two pipe sections to be joined, and an interposed soft metal calking ring which forms the exclusive packing for the joint, said ring having grooves for the purpose set forth.

7. A pipe joint composed of the two pipe sections, one having an enlarged or bell extremity and the other a shouldered extremity adapted to enter the bell extremity, and a cold soft metal calking ring inter osed between the pipe ends to be joine and packed tightlyin place, the said ring having grooves for the purpose set forth.

8. A soft metal calking ring provided with grooves for the purpose set forth.

9. A soft metal calking ring provided with longitudinally disposed grooves.

10. A soft metal calking ring provided with interior and exterior longitudinally ('lisposed grooves.

11. A soft metal calking ring provided with longitudinally disposed grooves arranged. both interiorly and exteriorly, but in staggered relation on the two opposite surfaces.

In testimony whereof I afiix my signature in presence of two witnesses.
